Title:
METHOD FOR PRODUCING (Z)-1,2,3,3,4,4-HEXAFLUOROCYCLOBUTANE
Document Type and Number:
Japanese Patent JP3840553
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing Z-1,2,3,3,4,4-hexafluorocyclobutane which is a useful compound affording a substitute compound for CFC or HCFC used as a refrigerant, a foaming agent or a detergent in high yield.
SOLUTION: This method for producing the (Z)-1,2,3,3,4,4- hexafluorocyclobutane comprises carrying out a hydrogenating reaction (hydrogen reduction) of 1,2-dichlorohexafluorocyclobutane as a raw material in the presence of a rhodium catalyst using especially ≥2 equivalents of hydrogen especially at 150-300°C.
